Steel Isoa New Close Type Hydraulic Quick Connect Couplings ISO 7241A

Steel ISO 7241-A Hydraulic Quick Coupling – CB-ISOA Series

Looking for a reliable ISO 7241-A quick coupler in carbon steel? Our CB-ISOA series offers improved valve design and superior shock resistance for high-performance hydraulic systems.
For full specifications, material options, and sizing details, please refer to our main CB-ISOA product page.

Compact Overview

The CB-ISOA coupling is designed for users who demand consistent performance in medium-duty hydraulic applications without needing full stainless steel corrosion resistance.
It combines ISO 7241-A compatibility, an updated internal valve structure, and hardened components to offer better reliability in construction, mobile equipment, and agricultural systems.

When to Choose CB-ISOA?

• You require a quick coupling that resists shock and impulse pressure.

• You prefer a cost-effective alternative to stainless steel.

• You work in general hydraulic systems (not exposed to corrosive fluids or coastal environments)

If corrosion is a concern, you may consider our stainless steel alternatives such as CB-SPM-10F-A or CB-SPL-10F.
